Has anyone else had a look at Scratch 3.
It's in preview and seems to be ok on the PC.
It doesn't work on a mobile size device (GUI is just a mess) for me.
Tried it on the Pi and things don't look good so far.
Layout is fine, but it brings it to a crawl and gives up before you even do anything.
(This is a new Stretch image, up to date).
Hopefully they get it working, but given it been in development for a long time, I thought it maybe work a bit better
Perhaps it just too demanding for a Pi3.
